The 5-patch series to follow this email extends KVM-hypervisor and Linux guest running on KVM-hypervisor to support pv-ticket spinlocks, based on Xen's implementation. One hypercall is introduced in KVM hypervisor,that allows a vcpu to kick another vcpu out of halt state. The blocking of vcpu is done using halt() in (lock_spinning) slowpath. Note: 1) patch is based on 3.4-rc3 + ticketlock

This series forms the kvm host part of paravirtual spinlock based against kvm tree. Please refer https://lkml.org/lkml/2013/8/6/178 for kvm guest part of the series. Please note that: kvm uapi: Add KICK_CPU and PV_UNHALT definition to uapi is a common patch for both guest and host.

This series forms the kvm host part of paravirtual spinlock based against kvm tree. Please refer to https://lkml.org/lkml/2013/8/9/265 for kvm guest and Xen, x86 part merged to -tip spinlocks. Please note that: kvm uapi: Add KICK_CPU and PV_UNHALT definition to uapi is a common patch for both guest and host. Changes since V12: fold the patch 3 into patch 2 for bisection. (Eric Northup)

This series replaces the existing paravirtualized spinlock mechanism with a paravirtualized ticketlock mechanism. The series provides implementation for both Xen and KVM. Changes in V10: Addressed Konrad's review comments: - Added break in patch 5 since now we know exact cpu to wakeup - Dropped patch 12 and Konrad needs to revert two patches to enable xen on hvm 70dd4998, f10cd522c -

The series provides implementation for both Xen and KVM.(targeted for 3.5 window) Note: This needs debugfs changes patch that should be in Xen / linux-next https://lkml.org/lkml/2012/3/30/687 Changes in V8: - Reabsed patches to 3.4-rc4 - Combined the KVM changes with ticketlock
